Six Indications of Permanent Pacing in Congenital Atrioventricular Block

In patients with congenital complete or high degree AVB, pacing is recommended if one of the following risk factors is present:

a) Symptoms

b) Pauses >3x the cycle length of the ventricular escape rhythm

c) Broad QRS escape rhythm

d) Prolonged QT interval

e) Complex ventricular ectopy

f) Mean daytime heart rate <50 b.p.m.

STEMI ECG Criteria and Universal Definition of MI

STEMI ECG Criteria and the Universal Definition of Myocardial Infarction: A Complete Guide for Clinicians Early and accurate diagnosis of acute myocardial infarction (AMI) remains the cornerstone of reducing morbidity and mortality in patients presenting with chest pain. Among all forms of acute coronary syndromes (ACS), ST-elevation myocardial infarction (STEMI) represents the most time-sensitive emergency, requiring immediate reperfusion therapy. This article provides a clinically relevant summary of the STEMI ECG criteria and the Universal Definition of Myocardial Infarction (UDMI), based on the latest consensus guidelines from the ESC, ACC, AHA, and WHF. --- 1. Understanding STEMI: Why Accurate ECG Interpretation Matters A 12-lead ECG remains the first and most critical diagnostic test when evaluating suspected myocardial infarction. STEMI is identified when there is evidence of acute coronary artery occlusion, producing transmural ischemia and characteristic ST-segment eleva...

The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.

2025 AHA/ACC Hypertension Guidelines Key points

2025 AHA/ACC Hypertension Guidelines Explained: A Clear Summary for Clinicians and Students Hypertension remains one of the most significant contributors to cardiovascular morbidity and mortality worldwide. With continual refinement of evidence and risk-based strategies, the 2025 AHA/ACC Hypertension Guidelines bring an updated, practical approach that clinicians can use in daily practice. To make learning easier, I’ve created a clean and modern infographic summarizing all major recommendations. You can download it below and use it for study, teaching, or clinical reference.
